"But years ago, he was briefed on Lucas’ plans for sequels, and how the Thrawn books would fit in. “The original idea as I understood it— and Lucas changes his mind off and on, so it may not be what he’s thinking right now – but it was going to be three generations. You’d have the original trilogy, then go back to Luke’s father and find out what happened to him [in the prequels], and if there was another 7th, 8th, or 9th film, it would be Luke’s children. The Thrawn Trilogy really would have fit into the gap,” the author said."
